Product Description
Specifications
Ordering Information

High termperature needle punched felt

Non-flammable and thermostable organic fiber

Offers extended bag life in low pH applications

helps reduce differential pressure across the baghouse

Operates in high temperature applications against acid attacks and is resistant to flex abrasion (unlike Fiberglass).

Not recommend for high concentration of alkalis at high temperatures.

Continuous operating temperature 460^oF (240°C)
